I was unaware this series was planned as a trilogy (I’m so used to Katee Robert doing LONG series!) but this was an excellent conclusion.

I was surprised at how little spice this book had, but I enjoyed seeing the three members of the relationship realize they wanted to be in a relationship. As other reviewers said, it did drag a little, but overall a solid read

Rebel in the Deep is a fast-paced, steamy adventure filled with danger, passion, and unexpected alliances. Katee Robert delivers a thrilling underwater fantasy with rich world-building and sizzling chemistry between the characters. Fans of her bold storytelling will love this daring, addictive ride beneath the waves.

"Rebel in the Deep" by Katee Robert is a thrilling, high-stakes adventure that kept me hooked from start to finish! The chemistry between the characters is intense, and Robert masterfully blends action, suspense, and romance. The world-building is immersive, and the plot twists had me on the edge of my seat. Huge thanks to the publisher for the ARC! I’ve already added a copy to my library system. If you're into fast-paced stories with captivating characters and plenty of drama, this one is a must-read. Highly recommend it!

I would like to thank NetGalley and Berkley Publishing Group for allowing me to read an eARC of this book in exchange for an honest review.

I am a HUGE Katee Robertfan, and have very much enjoyed this trilogy so far. the first 2 books were romantic and steamy and so good, and I had high hopes for this third installment. It was much less romantic and sexy, and instead more plot-driven than the previous books, but I really enjoyed the story and the ending.

Rebel in the Deep follows Nox, the Captain of the Audacity, who has been working with the rebellion for years, He is approached by the rebellion's leader, Siobhan, and Lizzie & Maeve (from book 2) to help save a noble who is headed for Council trial and possible execution. Surprise! It just happens to be Nox's ex Bastian (who broke his heart), and Nox is less than thrilled to be roped into what is certainly a suicide-mission to save him. With the help of Bowen & Evelyn (book 1), Nox's crew, magic and the elements, this merry and of misfits must race to save Bastian, and then Threshold itself from the perverse power of the Cŵn Annwn, led by Siobhan's evil sister, Morrigan. The mission turns out to have a lot of hardships, entanglements, hard feelings, and puts everyone's lives at risk. It is non-stop action all the way to the end.

Nox and Bastian have to put their past hurt aside, and Siobhan eventually helps then do just that in a very romantic and steamy. The throuple, whose feelings at times are a little hard to believe, are a good match. This book does a lot of things well, and is a good mix of action and romance. I think it was a very strong end to the trilogy, and a fun change of pace from her Wicked Villains & Dark Olympus series'.

I would highly recommend this trilogy to those who enjoy steamy romance, fantasy & magic!

Katee Robert’s Rebel in the Deep had an intriguing premise, but the execution fell flat. The story dragged, struggling to maintain momentum, and while the buildup promised an explosive climax, the payoff was underwhelming. The resolution felt far too convenient, wrapping things up without the depth or struggle needed to make it satisfying. While Robert’s writing and world-building had potential, the lack of tension in the ending made the journey feel less rewarding.

In the third and final installment of the Crimson Sails trilogy, the crew of the audacity take on a new mission: rescue Bastian, a noble who was captured and could be tortured for sensitive information about the rebellion. Nox and their crew are the only ones that could save him, but Bastian is Nox's ex, and things ended very poorly between them. Once rescued, Nox, Bastian, and Siobhan need to figure out how to move the rebellion forward...and how to move forward together.

This was a good ending to an interesting series. Rebel in the Deep was noticeably less spicy than other novels by Katee Robert, but there were a LOT of loose ends to tie up. I feel like there wasn't enough groveling from Bastian, but I still enjoyed the relationship between Nox, Siobhan, and Bastian. Since my library has the first two in this series, we will definitely be purchasing the conclusion.

I was lucky enough to get my hands on an early copy of Rebel in the Deep by Katee Robert, and wow—what a ride! This story is everything I’ve come to love about her writing: bold, steamy, and laced with just enough danger to keep your heart racing. The world feels both fresh and familiar, pulling you in with its dark twists and layered characters. There's a quiet intensity simmering beneath the surface that builds beautifully throughout the book.

Without spoiling anything, let’s just say that if you’ve been following this series, Rebel in the Deep delivers on all the tension and slow-burn payoff you’re craving. The dynamic between the leads is chef’s kiss, and the emotional undercurrents hit harder than expected. Katee Robert has once again proven she knows how to turn up the heat and still keep you deeply invested in the journey. You're going to love this one.

looking for a spicy read? katee robert is the QUEEN of spice, storylines that are easy to digest, and knowing how to pull you out of a slump. i had the best time reading this, the pacing was perfect and cannot wait to buy this when it releasses. thank you netgalley for the arc!!

This is the conclusion of this trilogy, and while it is less steamy than her other books, but it is a very satisfying conclusion! So well written.

Wow what a conclusion! I really enjoyed how this one turned out. I also really liked this last relationship group. It had enough history from the previous to keep you invested in them while also giving you the context you need. Another solid installment in Katee's catalog of series.

I had a fantastic time reading this book! I've loved this series from the beginning, and I love their writing, and I was excited to read Nox, Siobhan and Bastian's story! I wanted to see how the council and their predatory, tainted version of the Cŵn Annwn were down!

Oh, but the relationships between all of 3 of them was so great to read! Nox and Bastian were loves over a decade ago, but that ended when Nox followed through with their plan, and Bastian didn't. Bastian and Siobhan have been together for years now, but recently had a fight right before he got captured. And Nox and Siobhan are friends, working for the rebellion, but the attraction is there. I thoroughly enjoyed their dynamics!

The threat that they're against, the power, is clearly laid out in this book, when the rebellion is being threatened by having a pretty key figure getting captured, when they're not prepared for it. I was waiting with bated breath to figure out how they were finally going to win.

Rescuing Bastien was just part of this book, then there was making a plan, and executing it. I loved how the myths of the Cŵn Annwn became a vital part of the story, and the history they have in Threshold. Watching as it played out was so thrilling, I really enjoyed how it ended out playing out and where we left these characters!

Loved reading this book and I can't wait to read more by Katee Robert!

The final book in the Crimson Sails Trilogy, and YES, it is GREAT.

I will be honest though, I think book one was still my fav, but this book can take the second place spot lol.

Katee Robert could write a grocery list and I would be dying trying to read it.

I really loved this book. The plot was so well written. I usually read Katee for her spiceee, and not to say it wasn't there, but I feel like this book was more plot driven, AND I LOVED IT?!

I have been obsessed with Nox since the beginning, so diving deeper and seeing what he is all about was well awaited.

I LOVE THIS SERIES! Thank you so much to the publisher and to NetGalley for allowing me to read this final installment. It did not disappoint! I have been waiting since the first book to see how the overarching plot was going to be resolved, and I just had so much fun with the characters! I really enjoyed the world-building, and the magic system as well. It was really fun and unique!

While this book was not my favorite in the series, it was still a fun read especially if you love suspenseful romance.

The book seamlessly blends action, adventure, and slow-burning tension, particularly in the dynamics between Nox, Bastian, and Siobhan. As the trio navigates treacherous waters—both literal and emotional—Robert crafts an intense, character-driven story filled with longing, regret, and rekindled passion. The external threats, from deadly pirates to looming betrayal, add constant suspense, making every moment feel urgent and high-stakes.

While Rebel in the Deep delivers the rich world-building and swashbuckling adventure fans of the series have come to love, it’s the deeply personal conflicts that steal the show. Nox’s struggle to reconcile their past with Bastian while forging a new path with Siobhan makes for a compelling emotional journey.

A perfect conclusion to the Crimson Sails series, this book is an absolute must-read for fans of queer fantasy romance, found family dynamics, and second-chance love stories set against a thrilling, pirate-infused backdrop.

Nox has always been a character I was interested in learning more about, and I really enjoyed continuing to see the characters from the first two books in this one as well. There was only one spicy scene in this book (which feels a bit different from what I expected), but I don't think it was a bad thing to have this book focus so heavily on the plot. I was definitely motivated to finish this one quickly to see what would happen. Thanks to netgalley and Berkley romance for this ARC in exchange for honest review.

I love this series so much. I'm a huge Katee Robert fan. I love that she has such wonderful character representation. And what's not to like about hot pirates, vampires, and other magical creatures? Rhetorical question. Get this series in your life.

This was really fun. It was plot heavy with only one spicy scene which is not Katee’s usual I feel, but I loved it. My favorite of the series!

I like this world a lot. The overall story is really good, and I will continue the series if Katee writes more. I just could have used a bit more fleshing out of the romance in this one. It felt a bit lacking especially with Nox and Bastian. I wanted a better resolution of their previous relationship.

I was completely enthralled by Rebel in the Deep! The emotional depth of Nox's character, especially their tumultuous relationship with the noble Lord Bastian, kept me hooked. I loved how Katee Robert masterfully wove together elements of fantasy, romance, and adventure to create a story that was both thrilling and heartwarming. The tension between Nox, Bastian, and Siobhan added layers of complexity to the plot, and I found myself deeply invested in their mission to rescue Bastian. I particularly enjoyed the balance and the action-packed moments with the more intimate, emotional scenes. Nox's internal struggles and their journey to reconcile their feelings for Bastian and Siobhan were beautifully portrayed. The stakes were high, not just for the rebellion, but for the characters' hearts as well, making the story even more compelling.

Katee Robert's storytelling is truly exceptional, and I highly recommend this book to anyone who loves a mix of adventure, romance, and complex characters. I can't wait to see what she writes next!

A perfect conclusion to the trilogy! I loved these books. Such a fun and different read from Katee Robert. Thanks NetGalley and Berkley
